Ukraine-born oil and aluminum baron continues deal-making in chemicals, power plants, gas storage despite severe losses in his largest assets. Oil company TNK-BP shares down 63% over past year; an eight month power struggle finally resolved when chief executive was removed and new management put in place. Former German chancellor, Gerhard Schroeder, who has ties with Prime Minister Vladimir Putin, joining board. Things even shakier at aluminum giant, UC Rusal, which he formed with fellow billionaire, Oleg Deripaska, when they merged their companies. Firm's debts add up to $16.3 billion: $7 billion to foreign banks, $6.5 billion to Russian banks, and $2.8 billion owed to Russian richest man, Mikhail Prokhorov, for a 25% stake in Norilsk Nickel. Bankruptcy, nationalization and even sale to Chinese investors rumors are swirling. Meanwhile shares of Swiss electronics maker Oerlicon, in which Vekselberg holds a 33% stake, have fallen more than 90%.
